My system is not decent

Chapter 164 We Are Not Afraid of Disgrace

There are many inheritances and enough accumulation. As he deals with various problems, the inheritances in Chen Wenzhe's mind begin to be integrated.

For example, gold identification must be related to basic manufacturing.

The most important thing is that it is really not difficult to identify gold.

What's more, he also has a touch of gold skill as a blessing!

Since the density of this gold bracelet is not bad compared to that of gold, it means that the problem is not big.

However, at this moment, Chen Wenzhe discovered that there seemed to be some white bright spots on the surface of the bracelet.

Seeing this, Chen Wenzhe generally knew where the problem was.

Don't doubt the woman's intuition. Since this aunt said that there is something wrong with this pair of gold bracelets, there is a high possibility that there is really something wrong, otherwise she would not have tested it many times.

It is important whether the gold has white highlights.

If it can be damaged, use scissors to cut off the gold jewelry and observe its cut surface with a magnifying glass. If you see white bright spots, there must be a problem.

This is doped with iridium, and because gold and iridium cannot fuse together, white spots are formed.

The density of iridium is similar to that of gold, and some unscrupulous traders add iridium to gold jewelry to achieve the purpose of profit.

Using such fraudulent means is not uncommon in the jewelry industry.

Because the price of iridium is only [-] to [-] yuan per gram, but what about gold?It costs three or four hundred yuan.

This kind of profit margin, many merchants can't help but add some.

Of course, there are more ruthless ones, such as tungsten coated with a layer of gold, which is also easy to deceive professionals, because the density of tungsten is also similar to that of gold.

The most famous one is a domestic gold mining group, which used this method to produce a large number of gold bars and deposit them in the bank, and defrauded the bank for loans. They successfully defrauded [-] billion in cash.

Naturally, the gold bracelet couldn't be cut off for inspection. Chen Wenzhe could only use a magnifying glass to carefully observe the entire bracelet.

Under the magnifying glass, any flaws will be magnified.

"Did you find the problem?" Just looking at Chen Wenzhe's actions, the aunts knew that there was really a problem with the pair of gold bracelets.

"Iridium, a mineral, should be added. The price is a little cheaper. In fact, it's not a big problem. It doesn't affect the appearance, but the value is a little lower."

"Sure enough, there is a problem. It's not a price problem at all, but a deception." The aunt was already gnashing her teeth.

Chen Wenzhe was horrified when he saw it: "This kind of fraud is difficult to identify. There is also Vietnamese sand gold, which ordinary consumers can't see at all. Maybe the merchant is deceiving people!"

"Okay, I see, thank you, Boss Chen."

After finishing speaking, the aunt stopped talking.

Another aunt said: "Appraise one for me too. I bought it when I was traveling. Now that I think about it, I might have been cheated."

"Don't you have a certificate? Three nines of gold, it should be no problem!" another aunt said.

Chen Wenzhe took a look to see if he was a crow's mouth. This gold necklace is really a scam.

This is a fake Vietnamese alluvial gold, the cheapest kind of junk.

"Xiao Chen, look at the certificate, is it marked with three nines?"

"The certificate is indeed of the quality of three nines, but what is mentioned here is not the three nines of gold, but the three nines of Vietnamese sand gold."

Chen Wenzhe checked for a while, then put down the certificate, something was wrong, what's the use of looking at the certificate.

"Three nines of Vietnamese sand gold?" All the aunts were surprised. What's the difference?
The difference is huge, and Chen Wenzhe can only explain the pitfalls inside.

When you see the label of thousand pure gold or four nines, don’t misunderstand that it is pure gold. It is just for marketing. It is a thousand pure Vietnamese sand gold, which is not the same as thousand pure gold.

For example, some people think that milk tea does not contain milk, it is fake, this is not correct.

Milk tea is just a conventional name, the real milk tea is not a dairy product.

A small number of milk ingredients are just for different tastes.

Vietnamese sand gold contains a certain amount of gold, but it is not the gold we are talking about.

That is to say, Vietnamese sand gold is a kind of gold, unrefined gold, also called raw gold.

And what this aunt took out is not even Vietnamese sand gold.

Genuine Vietnamese alluvial gold jewelry will not visibly fade or fade, let alone turn black.

Even if there is a small amount of fading, it will only fade slightly after a long time, but it will not turn black.

Vietnamese alluvial gold does not have the problem of fading. From the simple appearance, there is no difference between pure gold and Vietnamese alluvial gold.

As long as you know how to do it, you can tell the difference with a little inspection.

Gold is softer, while Vietnamese sand gold jewelry is harder.

But most people can't feel it because they don't compare all day long, and they don't have this experience and feeling.

Vietnamese placer gold jewelry turns black, or fades obviously, usually other metals covered with gold, fake Vietnamese placer gold.

In movies or TV shows, when you go to Vietnam or Western Guangxi Province, you can see many men wearing a large gold necklace. Most of them are this kind of Vietnamese sand gold jewelry, not real gold necklaces.

This gold chain is relatively slender, naturally not as vulgar as the big gold chain, but they are essentially the same.

"This gold chain is not heavy, and the loss is not great."

"Even Vietnamese sand gold is man-made? These businesses are really devoid of conscience."

"Actually, you shouldn't buy things from tourist attractions."

"This old Town God's Temple is also a tourist attraction, right?"

"How can our tourist attractions in Dahai City be the same as those in other places? Besides, there used to be a mix of fish and dragons here, but now all the stalls have been cancelled, and all of them have become regular stores. No one dares to fake it, right?"

"Don't say that, in the antique business, people's counterfeiting is not called counterfeiting, it's called counterfeit, it's called high imitation, I'm sorry, shameless!"

"Okay, okay, Boss Xiao Chen still has business."

"Look at this painting of mine. I always feel that it is cheap to buy, and cheap is not good."

"Wait a minute, how much is a gram of real Vietnamese sand gold?"

Finally asked about the price, Chen Wenzhe really didn't want to use this to hit these aunts, because he had already seen that among the jewelry they wore, there was Vietnamese sand gold.

"Vietnamese alluvial gold jewelry is very cheap, and the price is not based on the gram." Chen Wenzhe said rather implicitly.

"How much is it? Tell me the exact price, we are not afraid of losing face." The mother of the pearl necklace said again.

"The price of each piece of jewelry is different depending on the gold content and workmanship. 100 grams of Vietnamese sand gold jewelry on the market ranges from 500 to 2000 yuan. Just like buying craft jewelry, there is no uniform price."

The aunts were speechless again. The cheapest one was five yuan per gram, and the most expensive one was only twenty yuan per gram. This is really no different from handicrafts.

And it is such a cheap Vietnamese alluvial gold, and some people actually fake it. This is no longer a conscience, but a lack of conscience.

"Xiao Chen is very capable, and this is the only way to open a shop here. The appraisal fee must be paid first."

The aunt who appraised the calligraphy and painting was more forthright this time.
